Faults were noted in the roof, but few extended into the coal (and therefore may have been joints or slips rather than true faults). The roof was black shale in the east ranging to gray-white shale in the west that was soft, heavy and treacherous. The main roof problems were in the northwest. Where possible the 14-inch top bench of the coal was left to support the roof, but in many cases the roof still came down. Caving extended to the surface in many cases, and this was reported to be the source of the water problems in this mine. The underclay floor was very soft and always wet in many places, so heaving was a common occurrence. Pyrite was present in lenses and stringers.
